On floatation glass production line produce high visible transmission than online sunlight controlling coated glass method.
Background technology
Modern architecture will almost use glass bar none, and many skyscrapers even use all-glass exterior wall knot
Structure, glass play go along with sb. to guard him, light transmission, sunshade, heat preservation, decoration the effects that.Sunlight controlling coated glass reduces solar radiant heat and enters
Interior saves refrigeration air-conditioner, is one of the glass product being most widely used.
Traditional sunlight controlling coated glass, since film layer is more to the absorption of visible light, absorption coefficient is big, all present compared with
Strong yellow tone, it is seen that luminous transmittance is low, is unfavorable for energy saving and beautiful.To body-tinted glass plated film, glass can be influenced
Self-tone；To common white glass plated film, undesirable visual effects are will produce.
On-line coating technology is, using the heat of high temp glass itself, to promote to react pioneer on floatation glass production line
Body decomposes, and can realize continuous production, does not need expensive equipment investment, overall cost is low, and plated film film layer and glass
Surface atom chemical bonds, are firmly combined with, and weatherability wear-resisting property is good, are convenient for secondary operation, therefore have obtained extensively
Using.
To avoid light pollution, standard GB/T/T50378-2014《Green building assessment standard》It is required that cladding glass can
Light-exposed reflectivity is less than 20%；GB/T18091-2015《Glass curtain wall light thermal property》Also clearly stipulate that glass curtain wall should use
Visible light reflectance is not more than 30% glass；The occasions such as major trunk roads, T fonts crossing should be not more than using visible light reflectance
16% glass.
Chinese invention patent CN1051534C discloses a kind of by way of chemical vapor deposition, the float glass process in molten tin bath
On glass matrix, the amorphous silicon film of one layer of boracic is deposited.The disadvantages of this method is that this glass visible light containing amorphous silicon film is anti-
It penetrates than high, reaches 40% or more, it is seen that luminous transmittance is low, and product but affects indoor lighting effect while sunshade, is not inconsistent
Close the design requirement of modern architecture.
In addition, the coated glass produced in aforementioned manners, since film layer structure is coarse, strong adsorption is easily stained with oil stain, impression of the hand
Deng, it is necessary to it is cleaned repeatedly with specific water and soft hairbrush, hot-working pre-treatment program is cumbersome.
To sum up, problem of the existing technology includes：Tone yellowing；Visible light reflectance is higher to lead to light pollution；Film layer
It is coarse not easy to clean etc..
Invention content
The present invention is exactly that tone yellowing present in existing method, visible light reflectance are higher to cause light dirty in order to solve
Dye, the problems such as film layer is not coarse easy to clean, provide a kind of film layer Clear colourless, are greatly reduced to the absorption of visible light, are visible
Luminous reflectance is adjustable, microstructure is more densified, the sunlight controlling coated glass that physicochemical property and hot-working character are excellent and
Its production method.
For this purpose, the present invention provides a kind of sunlight controlling coated glass, it is equipped with film layer, film layer includes matrix composition and doping
